Relative bias (%) in log scale (n = 1500). A. Association between Z and Y: Linear; Level of association between Z and X, Z and Y: Moderate. B. Association between Z and Y: Linear; Level of association between Z and X, Z and Y: Strong. C. Association between Z and Y: Non-Linear; Level of association between Z and X, Z and Y: Moderate. D. Association between Z and Y: Non-Linear; Level of association between Z and X, Z and Y: Strong. Robust Poisson: Red dotted lines. Log-Binomial: Blue solid lines.
